Title: Elevator control system
Inventor: SAKITA MASAMI
IPC: B66B1/14
Filed: 1997-04-03
Abstract: An elevator system for a multistory structure having a plurality of elevator shafts is shown which includes at least one independently movable elevator car in each elevator shaft.  A digital computer with memory is used to control elevator cars including the dispatch of cars from terminal floors.  A daily control parameter table in memory identifies a plurality of different methods of scheduling dispatch of elevator cars from terminal floors, groups of floors to be serviced by each elevator car, and cars in a shaft to be coupled for tandem operation.  The memory is periodically read for selecting for each elevator car one of said methods of scheduling dispatch and for identifying the group of floors to be serviced by the cars.  The selected method of scheduling the dispatch of cars is implemented and cars are limited to servicing the selected group of floors. One method of scheduling dispatch includes obtaining a measure of estimated passenger demand for travel in one direction that is incapable of being met by cars currently in service.  A passenger loading threshold limit for travel in the one direction is selected which may range from zero to maximum capacity of the elevator car to be dispatched. When the measure of estimated passenger demand for travel in the one direction that is incapable of being met by cars currently in service equals the passenger loading threshold limit a car dispatch signal is issued for dispatch of a car from the terminal floor.  Where a plurality of independently-operated cars are included in a hoistway, operation in either a coupled or decoupled manner is provided.

Title: Network security device
Inventor: LEVY BEN ZION
IPC: H04L29/06
Filed: 1996-09-06
Abstract: A network security device (10) is connected between a protected client (12) and a network (100). The network security device (10) negotiates a session key with any other protected client. Then, all communications between the two clients are encrypted. The inventive device is self-configuring and locks itself to the IP address of its client (12). Thus, the client (12) cannot change its IP address once set and therefore cannot emulate the IP address of another client. When a packet is transmitted from the protected host, the security device (10) translates the MAC address of the client to its own MAC address before transmitting the packet into the network. Packets addressed to the host, contain the MAC address of the security device. The security device (10) translates its MAC address to the client's (12) MAC address before transmitting the packet to the client (12).

Title: Internally latched subsea wellhead tieback connector
Inventor: SINGEETHAM SHIVA
IPC: E21B33/038
Filed: 1997-11-06
Abstract: A subsea wellhead tieback connector operatively used to connect to a marine riser pipe or a well conductor in a manner that will not unthread or unloosen the joints of the riser pipe being unlocked. The tieback connector operates with a novel internal latching mechanism having a hydraulic piston, an inner body that stretches and deflects in a unique manner resulting in compression spring forces at two locations, an expanding lock ring, a threaded adjustment ring, and a reaction ring. During operation the tieback connector creates an enhanced mechanical advantage to originate a required pre-load force without the necessity of having to generate a large hydraulic force that would otherwise be needed.

IPC: G01V8/16
Filed: 1996-05-13
Abstract: An optical seed counting system (36) for counting seeds (18) that are dispensed through a plurality of seed tubes (24) associated with a multiple row seed planter (12). Each seed tube (24) includes an optical sensor (38) having an emitter (66) and a receiver (68). The emitter (66) and the receiver (68) each include lens components for shaping an optical beam (170). Optical fibers (42, 44) connect the emitter (66) to an optical beam generating device (142) and the receiver (68) to an optical beam detecting device (148) both positioned remotely from the seed tubes (24). The detecting device (148) generates a pulse signal where the period of the pulses represents the intensity of the optical beam (170) in a sensing area (60). Seeds that are dispensed in the seed tubes (24) interfere with the optical beam (170) in a manner that effects the light intensity of the beam (170). Therefore, the change in intensity of the beam indicates the number of seeds (18).
